Oh man I love this game, it's so simple but really well made. The simple lightning and background really gives a serene atmosphere and you feel oddly attached to the blue ball. The controls feel fair and responsive, the blue thing that appears when you click is super satisfying. I wish there were sound effects and music because that would be awesome.
The final section feels really emotional, great storytelling !
Edit : I'm an idiot there's music I hadn't plugged in my headset
